So what does "power supply falling victim to "capacitor plague" mean, and is there a solution besides a new DVR?
Go to wikipedia and look up "capacitor plague" to find out why there are so many S2 and S3 power supplies with problems.
The problem is specific to mis-manufactured capacitors of the type of capacitor known as an electrolytic capacitor, and it's the mis-manufacturing (or outright counterfeiting) that's the problem--the replacements have to be electrolytics as well.
You'll want replacements that are the same rating in microFarads (uF), and the same rating in voltage (if you absolutely can't get that, go to the next higher value, for instance if the bad one is rated for 16V, go with 25V if you can't find the same uF at 16)
You must use Low ESR (Equivalent Series Resistance), which you may see referred to as low impedence, but look for caps that are specified to be Low ESR.
They must also be rated for 105 degrees (Centigrade/Celsius, not Fahrenheit), not the 85 degrees general purpose electrolytics are rated at.
You will not find what you need at Radio Shack, though if there's a Fry's nearby they might have them.
You might find this of interest
and I'm going to PM you a link to a page at a site which is blocked from mention on this site, and I'll include my email address in case it gets blocked in PMs as well.
Also go to this forum, click where it says Search This Thread on the right of the black bar near the top and enter "capacitor", and you'll find a lot of posts about the capacitor problem--they don't deal with your model, but the basics of replacing them are the same.
You should be able to get out for about $10 worth of parts, as opposed to $100 or so for a replacement supply.
It's not absolutely guaranteed that bad caps are the cause of your problem, but there's a very good chance of it.
Be sure to observe polarity when soldering in the new caps and remember rule number one:
ALWAYS KNOW WHERE BOTH ENDS OF THE POWER CORD ARE AT ALL TIMES
